Evolutionary psychology Flashcards
Homology
shared inheritied structures e.g vertebrate limb, frontal lobe (anatomy is the way it is because of the shared genes & linke for caring for young (genes shared due to genealogy)
Convergent evelution
result of natural selection
requirements for natural selection
variation, heritibility, differential fitness
variation (natural selection)
Different individuals in a population have different morphologies, physiologies, and behaviours.
Heritability
There is a correlation between parents and offspring in the contribution of each to future generations. (look similar)
Differential fitness
if resources are limiting, different phenotypes will have different rates of survival and reproduction because of differences in their design.
what does comparative psych tell us?
not just HOW minds work, but WHY they work the way they do
what tool makes us unique?
Langauage
Kanzi
Reactive, not grasp functionality of language
don’t grasp functionality
types of intelligence
Domain specific. domain general
Domain specific
specific to a particular domain e.g. perhaps there are specific modules for language, vision, social cognition (cant talk to other parts of the brain and integrate information)
Domain general
integrates information across different domains 30
Vygotsky - domain general
language plays a major role in shaping thought: as we develop we internalise our speech which then allows us to develop complex thought
Piaget - domain general
language provides labels for experiences but is not central to the development of thought
Probabilistic reasoning
involves making predictions about the likelihood of different event outcomes.
kia experiment
Kea seem capable of the type of domain-general, complex thought that in the past has been thought to require language…
Genotype
what is inherited
– The set of DNA molecules contained in nucleus
– A genotype particular to a trait
Phenotype
what develops from the genotype
– An organism’s physiology, anatomy, behaviour
chromosome
thread-like structures contained in the cell nucleus. Each chromosome is a DNA molecule. Chromosomes occur in pairs. Human
somatic cells usually contain 23 pairs
gene
a stretch of DNA that produces a specific protein
